Even the youngest children know big numbers: a thousand, a million, even a billion! But what comes next? A curious butterfly named Pebbles wants to know, too.

Follow Pebbles' globetrotting adventure and meet animal friends in exotic landscapes. From idyllic butterfly fields to scorching deserts, vast oceans, and the splendors of space, Pebbles is always eager to explore. This fact-filled science book for kids is overflowing with vibrant illustrations that pull the story forward.

Even as the numbers grow to unimaginable sizes, author Joey Benun finds imaginative ways to help kids grasp the concept. Big ideas feel manageable when compared to relatable, everyday objects, like sand and stars. Reading about math is even more fun with 'Did You Know?' trivia, 'Number Notes', and 'Science Spots' on every page!

Pebbles and the Biggest Number is perfect for independent elementary readers or a read-with-me introduction to toddler math. Plus, there's so much to re-read and explore after the story. Dig deeper with a kid-friendly science glossary, fascinating number visualizer, and supplemental online activities.

Will Pebbles ever find the biggest number? Flutter in and find out!
